To all who'r nit' may concern.-

Be a known that-I, DAVID A. Donn, a citi zen of'the United-States, and a resident of East Orange, inthe county of Essex and State of New Jersey; have invented certain new and useful Improvements in Mold-Sup ports, of which the following is'a description.

My invention relates to apparatus for use i inthe molding of phonographic sound-recon the interior surface thereof and adheres to the same when the mold is removed from the bath. l 4

In'the' use of the ap aratus contem lated by me the support itse f enters'thebat with the mold, an obviously upon the removal thereofits exterior will be coated with congealed material. If this material is allowed;- to set or harden thereon, it will be difficult to.

remove the same. It-is, however, necessary that this material be removed after each immers1on,"because OthQlWlSG it would increase in thickness with successive rmmersio'ns and interfere with the molding operat on.

" "My invention has for its object the provi- 'sion of an'improved support from which the congealed material may be eas' y detached t e features hereinafter set forth andclaimed.

. Reference is hereb- "made to the accompanying drawing, whic shows in sectional ele-' vation one form of device in Y which my invention may be embodied.

The mold-s n port is preferabl inthe formof a hollow bo y 1, decreasing s 'ghtly d i-- ameter from top to bottom and comprising a base 2, formed with a-circular'o ening 3, surroun dedby a seat 4, uponwhic the mold is adapted to rest, 'and having a: flat portion 5,

upon which a removable water-jacket may I i I rest, surrounding'the mold. The wall of the separated by an maybea'brass casting compr sm p .ta'l web 11,, av'ertical web 12, an st1fi'emng-.

support is composed of two cylindersfi and 7, air-space 8.. The base 2 ahorizon- -1"ib's H The= member 6 is secured to the Specification of Letters Patent. j A Application mm September 14, 605. sum 1a. 278.894.

web .11, andthe member fiis. secured to a rial the airfc'ontainedinthe chambers 8 and 10 will become heated. When the support is raised out of the bath, the heated air will rial which has congealed upon the exterior of perature and also because it. is a poor co n count of the proximity thereto of thewaterjacketed mold, so that thefcon'geal e'd p ate-i rial will either drop from the sifiportmby its own weight or can be very r'ea therefrom by the operator.
